What to Do When the Steering Wheel Shakes at 120 km/h on the Highway?

Perform a tire balance. Below is a related introduction about steering wheel shaking: 1. Reasons for steering wheel shaking: First, it could be due to uneven tire tread causing the steering wheel to shake. Unstable tires will start to vibrate when the car reaches a certain speed, and this vibration will be transmitted upwards through the car's drivetrain, leading to steering wheel shaking. Second, it could be caused by uneven surfaces on the brake discs or pads, resulting in shaking. 2. Methods to handle steering wheel shaking: Check if the tire tread is cracked. Aging tire rubber hardens and cracks, indicating that the tire has reached its replacement limit. Cracked tires have reduced grip and are prone to bursting due to external impacts while driving. Also, check if the tread is cut or punctured by nails. After a tire impact, promptly inspect the tread for bulges. Visit a tire repair shop to perform a tire balance using a tire balancing machine to identify the unbalanced areas and the required counterweights.
